Un fuerte terremoto de Mw 8.0 sacudió a Perú a las 2:41 am hora local este domingo 26 de mayo de 2019, desde un epicentro dentro de la Reserva Nacional de Pacaya-Samiria en la selva tropical del Amazonas.
A magnitude-8.0 quake shook deep below the Amazon Rainforest in Peru, causing extensive liquefaction and shaking from Colombia to Chile.
A magnitude-7.5 quake broke the same fault that produced a magnitude-8.0 quake in 2000, an extraordinarily short recurrence time that also broke all our rules
An open invitation for researchers to use these remarkable Costa Rica quakes as a collaboration laboratory
Two deadly and damaging quakes late last month were probably unrelated to each other.
The authors claim they found dynamic triggering of tiny aftershocks up to 275 km (150 mi)
from an M=7.2 mainshock in 2010, but they have not proved their case.
While exact repeats of earthquakes are rare, if the 1906 quake did strike again, what will be our excuse for being so unprepared?
In one case, the fault rupture and its associated seismicity had been shifted toward a volcano in support of the author’s hypothesis; in the other, seismograms from temporary near-fault stations had been manufactured. In both cases, evaluation committees and universities called for retractions.
The magnitude 7.1 earthquake, which struck Mexico City on 19 September 2017, caused devastation in the city and its surroundings. 369 people died, 57 buildings collapsed, and a much larger number was seriously damaged.
A new model joins two others in confirming the hazard posed by the tectonic forces that are squeezing and shearing greater LA.
India is one of the countries with the most earthquake-related deaths. Just in the past century, over 100.000 people have died due to earthquakes in the country (Bilham, 2009)
The megathrust fault lacks large subduction zone earthquakes in this region. What do these extensional earthquakes tell us?
The earthquake is surrounded by recent great quakes; whether one could strike here is uncertain
The Coquimbo region has an unusual, increasing seismicity that may be preparing the area for a very large earthquake – Prof. Raul Madariaga
One may think that these quakes are small, so why do they matter? Why should I care?
The partial shutdown could make things worse
Japanese authorities declared the Jan 3 shock to be an independent event; we argue that it was a product of the 2016 quake, which profoundly changed the hazard.
In Pennisi, the statue of Saint Emidio, protector from earthquakes, collapsed.
Tsunami, Eruption, and earthquake risk is not over
The Alaskan Megathrust was responsible for the M=9.2 Good Friday earthquake in 1964.
While the fault that ruptured in last week’s Kos-Bodrum earthquake is still up for debate, we now know that the M=7.7 earthquake in the Commander Islands ruptured the Bering Fault Zone
At 12:02 a.m. local time, a Mw=7.8 (per USGS), Mw=7.5 (per GNS Science, NZ) earthquake struck New Zealand’s South Island, and caused tsunami warnings to be issued for all of New Zealand’s east coast.
It’s been over four months since we wrote about the powerful Kumamoto quake sequence: The 15 April 2016 Mw=6.2 (Mjma 6.5) Kumamoto, Japan, shock, which was succeeded 28 hours later by the very damaging Mw=7.0 (Mjma 7.3) shock on the same fault system. We can now give you a preview of crucial new discoveries by Japanese and other researchers.
Could this happen again now? As with precursory swarms, progressive earthquake sequences are uncommon.
Was the M=6.1 a foreshock of the M=7.0, or was the M=7.0 an aftershock of the M=6.1?
